Arizona Mosquito Species

Mosquitoes have the well-earned reputation as being a nuisance, consuming our blood and injecting saliva during feeding, which causes itching and other reactions. The pests are also known for being transmitters of disease. However, many people are surprised to learn that mosquitoes don't just feed on blood, but also on sweets, such as plant nectar. Only females take a blood meal and must do so to produce eggs.

Lots of people know that mosquitoes have four life stages in their cycle of life: eggs, larvae, pupae and adults. However, many are somewhat taken back by the large numbers of mosquitoes in Arizona, especially since the state is generally thought to dry and not very conducive to these pests.
